TENT 1 JAMES F. PATTON AND JOHN E. MCALLISTEB, OF CLEVELAND, OHIO. 2

Application filed May 12,

To all whom it may concern:

Be it known that we, JAMES F. Pivr'roN and JOHN E. MoALLIs'rnn, citizens of the United States, residing at Cleveland, in the State of Ohio, have invented new and useful Improvements in Milling Machines for Continuous Milling, of which the following is a specification.

Our invention relates .particularly to a machine which operates upon formed blanks to convert them into castellated nuts. In general castellated nuts are hexagonal in form at their base and are provided with an upper cylindrical portion. Through a portion are milled slots which are perpendicular to the lines forming the sides of the formed blanks. It is an object of our invention to mill these slots in the formed blanks.

Various objects and advantages of our invention will be set forthhereinafter.

For the purpose of more fully disclosing the nature and advantages of our invention, we will describe the specific embodiment thereof illustrated in the accompanying drawing. It should be understood, however, that our invention is capable of various modifications and, therefore, it is not limited to the particular structure illustrated.

In the accompanying drawings Figure is a plan view of one form of our machine. Fig. 2- is a plan view of a portion of the machine on a larger scale. Fig. 3 is a sectional view taken on the line cr -a of Fig. 1. F ig. t is a section on the line c-c of Fig. 1 and Figs. 5 to '12 show details of the mechanism.

e provide a hopper 1 from which the formed blanks 2 drop into pockets in a feed wheel 3 which is mounted in a shaft which is rotated as hereinafter described.

As shown in F ig's. 1'1 and'12 the feed wheel consists of a central cylinder 5 between two flanges 6. The flanges are'pro-videdwith inwardly extendingremovable teeth 7 held in place by screws 8. It will be seen that the teeth are beveled at their inner ends so as to correspond to the form of the formed blanks 2. It will be understood that the teeth 7 illustrated in'Fig. 1'1 are adapted for the particular formed blankQ shown in position in the drawings. Formed blanks of other sizes-or other contours may be accommodated by substituting; for the teeth 7 herein shown, other suitably formed teeth.

MILLING MACHINE FOR CONTINUOUS MILLING.

1919. Serial No. 296,390.

Thefeed wheel 3 is loosely mounted on the shaft t'but is provided in its end'with teeth that the feed wheel turns with the shaft.

Fig. 11 and so draw the teeth 9 and 10 out-10f engagement. In this condition the feed wheel 3 may be adjusted about'the shaft4' so as to properly receive-the formed blanks from the hopper 1.

Extending between the teeth 7 and over the central cylinder 5'of the feed wheel 3 is a guide'b'ar 13 'showninperspective in Fig. 9. This-guide bar forms a bottom forthe pockets formed betweenthe' teeth '7 to receive the formed blanks and as the feed wheel revolves, the 'formediblank's are 'forcedalong this guide bar into the channel 14 int0 which the end of the guide ban-enters andis fastened.

The channel 14 is-at right angles with the axis of the feed wheel so that as the wheel rotates it forces the formed blanks 2 through the channel. The channel may be of any suitable length and at a proper point in it we provide a cutter 15 which is adapted to 'be rotated in a manner hereinafter described'a'nd cuts a slot across one diameter of the formed blanks as they pass by the cutter. In the particular embodiment of our invention shown in the drawings, the cutter consists of the usual disc mounted over the channel 14 and acting upon the tops of the formed blanks as they are passed under the cutter. The channel is provided with retaining plates 16 which hold the formed blanks in the channel. These retaining plates do not at all times bear upon the formed blanks but allow them free passage and at the same time prevent the formed blanks from buckling or turning pendicular to two of extending through the base of the channel and surrounded by coil springs 19 which act between the bottom of the channel base 20 and nuts 21 on the ends of the shanks to hold the pressure bars 17 down. The pres sure bars have noses. 22 projecting over and in engagement with the formed blanks in the channel. As shown in Fig. 7 the noses of the pressure bars have a fiat portion between two rounded ends so that the formed blanks may be readily fed under the pressure bars in their travel through the channel. It will be readily seen that the effect of so holding'the formed blanks while being acted on by the cutter will be to produce a slot of uniform depth.

It will be remembered that the teeth 7 in the feed wheel 3 are formed and arranged to grasp the formed blanks in such a way asto force them forward while in direct contact with each other on their sides in contradistinction to their angles. The relative proportions of the teeth, feed wheel and formed blanks is such that after the formed blanks leave the hopper they are always in contact with each other so that there is a continuous train of formed blanks passing through the channel and they are forced under the cutter by a continuous forward movement and not by an intermittent movement. The arrangement ofthe formed blanks in the channel and when the cutter acts upon the formed blanks is such that the slot milled in the formed blanks is performed blanks.

In order to complete the milling operation on. the formed blank, which requires the milling of two additional slots at an angle with reference to the first milled slot, it is necessary to feed the formed blanks. when once cut; at an angle to their first cut and then again at an angle to both the first and the second slots.

when so turned each blank will have in it three milled slots extending entirely across the formed blank and perpendicular to the Y beyon'd that a third channel 24 at an angle to the channel Associated with each ofthe channels 23 and '24 are, corresponding cutters 1.5and their associated pressure bars and appurtenances, as well as feed wheels si milar'to the feed wheel 3 for forcing the formed blanks through the channels and underthe cutters.

In order to insure that the formed blanks will be turned properly when passing from one channel to the other, we have pro the side faces of the Y channel and under the cutter.

from one channel to the other and over the It is obvious that if simi-- lar cuttlngmechanisms are arrange to act upon the formed blanks in'their movement wters 15.

associated with the channel 14.

wheel 25 mounted on a perpendicular pivot 26 adjacent to the path of the formed blanks and arranged to receive a formed blank between each pair of points. The inner angle at the turn of the channel consists preferably of a separate plate 27 having its point cutaway. This-plate 27 is held by screws 28 in the channel base 20 and the screw holes in the plate are so formedthatthere is a little room for movement so that when the screws are loosened the plate and its guiding side may be slightly adjusted to accommodate the particular formed blanks being operated upon. Opposite the plate 27 in the outer wall of the channel at the angle is a guide 29 adjustable under the head of the bolts 30 which engage the channel base 20.

The adjustable guide 29 may be so adjusted to receive the formed blanks, is properly.

adjusted on its shaft to grasp the formed blanks as they pass from the transfer wheel 25 and force them as so turned through the Extending central cylinder 5 and between theteeth .7"

of the feed wheel. 3 at an angle, is an angular guide bar 31. shown in plan in Fig. 8 WllJCll acts as a bottom for the pockets formed by the teeth 7 and insures a smoothv even passage way for the formed blanks from one channel to the other and while being turned.

The feed wheels and the cutters may be driven by any suitable mechanism. For example wehave shown a verticalshaft 32 carrying two horizontal pinions 33 and 34. The upper beveled ninion 34 engages the pinions 35 on the shafts carrying the cut- The lower beveled opinion 33 cngages a pinion 36 on a jack shaft 37 which in turn carries a pinion 38 engaging a pinion 39 on the shaft 4 of the feed wheel 3 Also engaging the lower pinion 33 is a pinion 40 on the jack shaft 41 which in turn carries a pinion 42 engaging a pinion 43 on the shaft 4 of the feed wheel 3 associated with the channel 24. The jack shaft 41 also carries a pinion 44 engaging a pinion 45 on the tical shaft 32 is properly rotated by "a motor or other suitablemechanism (not shown) it will. in turn, drive the three feed wheels in the proper direction to force the formed blanks forward through the charm ls and at the same time rotatethe cutters in the opposite direction, that is so that-the bottom or cutting points of the cutters will be operating in a direction opposite to the direction of movement of the formed blanks. in
